I upgraded to the eco-drive from a watch that recharged by wrist motion. So far I'm a lot happier with the eco-drive. It holds a charge a lot longer, so it's not a problem to leave it unworn for a day or two. I didn't like the green military style band on this one, but it was easy to swap for a leather 20mm band. The stock band was a tad small for my wrist. I would expect a lot of men would need to swap it. The numbers look big in the picture, and they're big on the watch. I like the big numbers, others might not.
Keep time with military precision while adding a unique edge to your wardrobe with the Citizen Eco-Drive Men's Chronograph Canvas Watch. Featuring the clean look and the rugged dependability of a stainless steel case and bezel, this timepiece relies on the unique Citizen Eco-Drive movement system, so you never need to replace its battery.
Eco-Drive is an advanced, technical system that uses a thin solar panel under the dial to convert light energy from any source into electrical energy used to run your watch. Also playing a key role in this unique system is a special energy storage cell that greatly increases the efficiency and dependability of using light as a power source. As an added benefit, Eco-Drive power doesn't utilize the harmful chemicals contained in traditional batteries, so it's an excellent environmental choice as well.
